Sunny Island

Off-Grid Inverters

The flexible system manager

SMA offers several options for installing world class, stand alone energy systems. Featuring AC coupled technology, the Sunny Island inverter is an intelligent system manager that creates a high quality, self-sufficient AC grid and protects sensitive batteries, extending system life.

In the Sunny Island system, electricity generators and loads are flexibly integrated. PV and wind energy systems, diesel generators, hydro power or CHP (Combined Heat and Power) can be modularly integrated in a large off-grid system. Equally adept at grid-tied back up, the Sunny Island system can also be easily designed to provide reliable power in the case of a grid outage.
